公知のように、果汁、ＵＨＴ（超高温熱処理）牛乳、ワイン、トマトソース、その他などの多くの液体または注入可能な食品が、滅菌パッケージ材料から作られたパッケージに入れて販売されている。 As is known, many liquid or injectable food products such as fruit juices, UHT (ultra high temperature heat treated) milk, wine, tomato sauces, etc. are sold in packages made from sterile packaging materials.

典型的な例は、積層されたシートパッケージ材料を折り畳んで密封することによって作られる、Ｔｅｔｒａ Ｂｒｉｋ Ａｓｅｐｔｉｃ（テトラ・ブリック・アセプティック）（登録商標）として公知の液体または注入可能な食品用の平行六面体形状のパッケージである。 A typical example is the liquid or injectable food parallelepiped shape known as Tetra Brik Aseptic® made by folding and sealing laminated sheet packaging material. is a package of

特に図１を参照すると、パッケージ材料２は、繊維性材料、例えば紙、またはミネラル充填ポリプロピレン材料から作られてもよい、剛性および強度のための基層４、ならびに熱密封プラスチック材料、例えばポリエチレンフィルムから作られ、基層４の両側を被覆する第１の被覆層５ａおよび第２の被覆層５ｂを含む。ＵＨＴ牛乳などの長期保存製品のための無菌容器の場合、パッケージ材料２は、ガスバリア材料、例えばアルミニウム箔またはエチルビニルアルコール（ＥＶＯＨ）フィルムから作られた遮断層６も含み、遮断層６は第２の被覆層５ｂの上に重ね合わせられ、次いで熱密封プラスチック材料、例えばポリエチレンフィルムから作られ、最終的に食品に接触する容器の内面を形成する第３の被覆層５ｃで被覆される。換言すると、第１の被覆層５ａ、第２の被覆層５ｂ、遮断層６および第３の被覆層５ｃは、パッケージ材料３を生産するときに連続シートの形で基層４に貼付される積層を画定する。 Referring specifically to FIG. 1, the packaging material 2 is made from a fibrous material such as paper, or a base layer 4 for stiffness and strength, which may be made from a mineral-filled polypropylene material, and a heat-sealed plastic material such as a polyethylene film. It is made up of a first coating layer 5a and a second coating layer 5b covering both sides of the base layer 4 . In the case of sterile containers for long-term storage products such as UHT milk, the packaging material 2 also includes a barrier layer 6 made from a gas barrier material such as aluminum foil or ethyl vinyl alcohol (EVOH) film, the barrier layer 6 being the second and then covered with a third covering layer 5c which is made from a heat-sealing plastics material, for example a polyethylene film, and forms the inner surface of the container which will eventually come into contact with the food. In other words, the first covering layer 5a, the second covering layer 5b, the barrier layer 6 and the third covering layer 5c form a laminate that is applied to the base layer 4 in the form of a continuous sheet when producing the packaging material 3. define.

本発明により、飲用ストロー、具体的には飲用ストローの先端部の剛性を増加させることができる。この方法で、使用者は公知の飲用ストローの場合よりはるかに容易に容器の突き刺し部を壊すことができる。 The invention makes it possible to increase the stiffness of the drinking straw, in particular the tip of the drinking straw. In this way, the user can break the piercing portion of the container much more easily than with known drinking straws.

加えて本発明により、それに応じて飲用ストローの費用を増加させることなく飲用ストローの剛性を非常に高めることができる。これは、剛性増進手段を形成するように、管体を折り曲げ、永久に変形させることによって、増加した剛性が獲得されるからである。換言すると、増加した剛性は、公知の飲用ストローに比べて強い（かつ高額な）材料を使用することによるのではなく、管体に剛性増進手段を提供することによって獲得される。この方法で、より効果的な突き刺し作用が、公知の飲用ストローと同じ材料を使用することによって（したがって実質的に同じ費用で）獲得され得る。 In addition, the present invention makes it possible to greatly increase the rigidity of the drinking straw without correspondingly increasing the cost of the drinking straw. This is because increased stiffness is obtained by folding and permanently deforming the tube to form the stiffness enhancing means. In other words, increased stiffness is obtained by providing the tube with stiffness enhancing means, rather than by using stronger (and more expensive) materials than known drinking straws. In this way a more effective piercing action can be obtained by using the same materials as known drinking straws (thus at substantially the same cost).

さらに飲用ストローの増加した剛性は、突き刺し部を壊すときだけでなく、飲用ストローの取り扱い中および輸送中にも好都合である。本発明によるより剛い飲用ストローは、実際に損傷および変形にはるかに耐性があり、損傷および変形を受け難い。 Furthermore, the increased rigidity of the drinking straw is advantageous not only when breaking the piercing, but also during handling and transportation of the drinking straw. Stiffer drinking straws according to the present invention are actually much more resistant and less prone to damage and deformation.
